HEEL CLAMP FOR SKATES.

Application filed August 25, 1925, Serial No.

Hitherto the heel clamps of skates have usually been provided at their upper ends With toothed or cutting edges formed by bending in the ends of the side pieces of the clamps, which edges are pressed into the leather of the heel and thereby hold the skate firm. It is however not possible to make these edges sharp and strong enough to be able to press them in the leather to a suflicient depth without great strain.

According to the invention these drawbacks are avoided by providing the side pieces of the clamps at their upper ends with a fiat and wide steel cutting edge, which is separately inserted, and owing to its small thickness can engage above the outer surface or the rubber tread of the heel in the strong leather and thus effect a secure attachment. The steel plates which are inserted in the side pieces of the clamps are suitably arranged with their cutting edges inclined at an angle to the surface of the sole. The result is thereby obtained that not only is splitting of the leather avoided owing to the cutting edges engaging obliquely over the seams between the layers of the leather in the heel, but the skate is also reliably se cured and is at the same time prevented from slipping lengthwise.

This security against longitudinal displacement may suitably be still further increased by inclining the two steel cutting edges towards opposite sides. The skate is then so securely held in its longitudinal direction that the stop which is otherwise provided at the rear end of the skate can be dispensed with so that it becomes possible to fit the skates to boots of a number of different slzes.

An embodiment of the invention is illustrated by way of example in the accompanying drawing, in which Fig. 1 shows the heel portion of a skate in lan; p Fig. 2 is a front elevation, and

Fig. 3 a side view, in which the front side piece of the clamp has been broken away and is illustrated separately in Fig. 4:.

In the example illustrated, a is the heel plate of a skate and b are the two side clamping pieces which are movably fitted thereto and can be adjusted as to width in the usual manner by means of a threaded spindle which is not illustrated in the drawing. The upper ends of the side pieces I) are each provided with a slot 0 in which the somewhat 52,286, and. in Germany August 29, 1924.

reduced rear end shank or tongue portion of a thin steel plate cl is inserted from the in ner side of the clamp. The steel plate is thus supported with its shoulders against the inner surface f of the side clamp 72 and its end which projects beyond the outside of the side clamp is provided with a hole in which a pin 9, which fixes the plate (Z in its position, is riveted. The plate d is preferably made of good quality steel and is provided on the inside with a sharp edgeh so that, when the side pieces are screwed together, it can'easily be pressed deeply into the leather of the heel without great exertion.

The steel plates (Z fitted on the side clamps are arranged with their cutting edges h inclined to the sole and so that these the cutting edges are inclined in opposite directions. The joints between the small sheets of leather forming the heel are therefore overlapped obliquely so that any splitting of the leather is avoided with certainty and a thoroughly reliable fastening of the skate is obtained. The skate is so securely held to the boot by means of this new fastening device that the stop at the rear end of the heel plate, whioh'has hitherto usually been provided, can be dispensed with and, therefore, not only does an adjustment of the skate in the longitudinal direction of the heel become possible, but the skate can be used also for boots of greatly difi'erent sizes.

The invention is of course not limited to the example illustrated. but other constructions are possible, thus the cutting edge of the steel plate instead of being inclined to the sole might also be arranged parallel to it and another kind of fastening for the steel plate and another shape for it might be chosen.

I claim:

1. A heel clamp for skates comprising cooperating side clamping members, and heel engaging elements carried by said clamping members and extending inwardly therefrom, said elements comprising thin metallic plates having sharpened edge portions to bite into the sides of the heel.

2. A heel clamp for skates comprising a heel plate, angular side clamping members reciprocably mounted on said heel plate, and on each clamping member an inwardly ex tending knife-edged member.

3. A heel clamp for skates comprising cooperating side clamping members, and heel .carried by the upturned portions of said engaging elements carried by said clamping members and extending inwardly therefrom, said elements comprising thin metallic plates having sharpened edge portions to bite into the sides of the heel, the respective plates being inclined at an angle to the longitudinal axis of the skate.

4. A heel clamp for skates comprising c-o operating clamping members having upturned portions, and heel engaging elements clamping members, said elements extending inwardly from said upturned portions of the clamping members and comprising thin metallic plates each having a sharpened inner edge to bite into the side of the heel, the respective plates being arranged at reverse oblique angles to each other and to the longitudinal axis of the skate.

5. A heel clamp for skates, comprising cooperating side clamping members having openings in their inner faces, and heelengaging plates fixedly secured in the openings of the clamping members and having their heel-engaging edges sharpened, the

7. A heel clamp for skates, comprising co-- operating side clamping members having openings therein, heel-engaging, thin steel plates having inner knife edge and outer reduced shank portions inserted from the inside through the openings in the clamping members so as to protrude therefrom, and

a pin passed through the outwardly protruding end or" each shank portion for securing the plates in position.

In testimony whereof I aiiix my signature.
